It's $.ajax and post method. So far, I haven't been able to figure any way to cause the $.ajax call to wait for the images to be processed before continuing.
I've look at ajaxComplete, ajaxSuccess, using cfthread in the cfc method, breaking the script into two parts, using async:false setting in the $.ajax settings... nothing seems to have the desired effect. If there was just some way I could get a variable or something that would only be sent once the images completed processing and then somehow to set up something to wait for that data to show up, as in a loop within the call back or something. But I can't think of anything I could use like that. It seems no matter what I do on the CF backend in the cfc, the ajax call is going to skip right over the processing and head back to the calling page and I can't find a way to control the events in the callback.

Rick... Are you using the GET/POIST methods, or using the AJAX methods from within jQuery? AJAX is gonna be your best bet as it's got more options. andy -----Original Message----- From: Rick Faircloth [mailto:[email protected]] Sent: Tuesday, September 22, 2009 10:13 PM To: cf-talk Subject: RE: CF & jQuery - How to delay ajax completion until images are processed... Thanks for the tip, James... I tried to use the setting "async: false" in the ajax parameters, but that didn't seem to have any effect. I wish I could somehow let the image processing continue even if the "close" button on the success dialog is clicked. But that causes the processing to stop. It might work if I weren't re-writing the property list on the screen after adding a property, but that defeats the whole purpose of using ajax. Clients have commented about the length of time it takes for all the image processing to occur. I even tried putting the image processing part of the cfc method into a cfthread, but that didn't seem to help, either. I'll check out your link...perhaps that's the answer.

It sounds like you need a synchronous request e.g.: http://stackoverflow.com/questions/133310/how-can-i-get-jquery-to-perform-a- synchronous-rather-than-asynchronous-ajax-req Of course, if you have to wait for a response, it may be worth simply doing a normal post rather than using ajax. mxAjax / CFAjax docs and other useful articles: http://www.bifrost.com.au/blog/ 2009/9/23 Rick Faircloth <[email protected]>: > > Got a combination CF & jQuery question for those of you who use > both.usually, I can get > > a better response from folks who use CF & jQuery than I can from those who > use only jQuery. > > > > I've got an ajax call (not AJAX call.) that inserts property data into a > database then processes from 1 to usually > > no more than around 10 images, creating multiple sizes, etc. > > > > The problem I'm having is that the ajax call, being asynchronous, returns > back to the calling > > page and continues executing instructions before the images are all > processed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Want to reach the ColdFusion community with something they want?
